LOUIS H. PORTER, OF ROOKDALE, TEXAS.

MILK-COOLER.

SPECIFICATION forming part of Letters Patent No. 416,423, dated December 3, 1889.

Application filed July 12, 1889. Serial No. 317,305. (No model.)

To all whom it may concern:

Be it known that I, LOUIS H. PORTER, residing at Rockdale, in the county of Milam and State of Texas, have invented a new and Improved Milk-Cooler, of which the following cylindrical in shape, having a closed bottom A. To the lower part of this receptacle A is secured a curved tube 0, the tube being secured at its center to 'the can A, and an opening leading from the interior of the can to the interior of the tube. This tube 0 is formed of suificiently-fiexible material to permit of its being bent around the can or other vessel in which the milk to be cooled is placed. Because of its pliabilityand cheapness a quarter-inch lead pipe is used for the tube 0,

and the inner side of this curved tube is formed with a series of small apertures 0'. Before the tube 0 is curved awire m, ofsome non-rusting material, is passed through the tube, being of such length that its ends project beyond the ends of the tube. The diameter of this wire is smaller than the bore of the tube, and the projecting ends of the wire are bent out at an angle, and the ends of the tube C are closed by soldering. The wire in gives strength and rigidity to the tube 0 and prevents its breaking or mashing in, which would otherwise beliable to occur during the repeated adjustment of the tube 0 around the same or different sized vessels. The projecting bent ends of the wire on furnish a convenient hold for the fingers in bending the tube around the milk can or vessel.

The bucket R or churn or other vessel in which the milk, meat, or fruit to be kept cool is contained is wrapped or inclosed in a sack S or wrapping of any other suitable textile material, this sack being preferably closed at the bottom, as it gives more evaporatingsurface, and the vessel R should not be set fiat on the ground or floor, but be slightly raised above the same to permit of free passage of the air underneath it. The tube 0 is then bent around the upper part of the bucket R, and it will be seen that the water let into the water-receptacle A will run into the tube 0 and out through the series of perforations C in its inner side, being thus distributed entirely around the upper part of the bucket R, when itwill soak down through the cloth or sack around the Vessel, thus keeping the en- .tire surface of the bucket wet as long as water is kept in the receptacle A. The cloth S being thus kept continually and evenly wet by the equal distribution of the water which the perforated tube 0 effects, the evaporation of the water from the cloth or sack will keep the bucket and milk thoroughly cold, it being best to place the vessel when in use as much in the wind as possible.

B'indicates the water-reservoir, adapted to fit within the receptacle A, closed at its upper end (Z and having at the said end a handle 19 for lifting it in and out of the receptacle A. The lower end of the water-reservoir B is closed and is formed'with an opening f, which is controlled by an upwardly-openin g valve 6, having a downwardly-projeoting pin g, as shown. The water-reservoir is filled by turning its lower end up, so that the valve 6 will fall in when the water is poured in the reservoir through opening f, and the reservoir is then reversed with its right end up and placed in thereceptacle A. The water-reservoir Bis shorter than the "receptacle A, and when the reservoir B is placed in the receptacle A, with the rim 1) of itsupper end resting upon the upper edge of the receptacle A, the lower end of the valve-pin 9, coming in contact with the opening f, when air will naturally pass up into the reservoirand cause the water to flow out as at first, the water being thus automatically fed from the reservoir into the receptacle A. The receptacle A has a loop Z at its upper end, by means of which it can be suspended to a post, tree, or wall, as shown in Fig. i. The receptacle A has at its lower end a socket "6, in which the upper end of a footrest it is fitted, and has at the opposite side of its lower end a horizontal socket h, in which the upper end of a bracket jfits. The bucket B may rest upon the floor or ground, as shown in Fig. 3, when the receptacle A rests on the foot-rest 7t and has the upper end of a hook n, which is secured 011 its forward side, as shown, caught over the top rim of the bucket. The tube 0 is bent around the bucket, and a cord or wire 3 tied around the bent ends of the wire m. hen the receptacle A is suspended by its loop Z from a post, as shown in Fig. 4, the bracket j is placed in position and the bucket rests upon the horizontal lower part of the same, while the hook at is caught over the top rim of the bucket.

It will be seen that my invention can be used without the reservoir B by filling the reservoir full of water, as it will only ooze out of the small perforations of the tube 0, which are pressed against the cloth around the bucket; but the reservoir, with its valve, causes the same quantity of water to last longer. It will be readily seen that more than one tube 0 can be attached to one recepticle A to cool two or more buckets by one reservoir and receptacle. The receptacle A can have a pipe E leading from its lower end, closed at its outer end, and having a number of perforated tubes G connected to it by T-couplings D, the entrance of water into each perforated tube 0 being controlled by a stop-cock a, so that any one or more of the tubes 0 can be used. The flexible tube C can be easily fitted around difierent sized vessels.

My invention possesses this advantage over all coolers that work by capillary attraction, that the water will always flow freely through the perforated tubes C and run down the sack S, while in those coolers where the water is drawn up by a cloth by capillary attraction, if the cloth becomes the least oily or greased, which often happens, it will not draw up the water.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. The combination of a receptacle covered with a wrapping of textile material, the waterreceptacle A, and the curved perforated tube C, communicating with the receptacle A, substantially as set forth.

2. The combination of a receptacle covered with awrappin g of textile material, the waterreceptacle A, the curved perforated tube 0, communicating with the receptacle A, and the wire m, substantially as set forth.

3. The combination, with the water-receptacle A and the perforated tube C,communieating therewith, of the reservoir B, closed at both ends and having at its lower end the opening f and valve 2, having the valve-pin g, substantially as set forth.

4. The combination of a receptacle R, covered with a wrapping of textile material, the water-receptacle A, having the hook n and socket 2', the curved perforated tube 0, communicating with the receptacle A, the footrest It, and the reservoir B, closed at both ends and having at its lower end the openingff and valve 6, having the valve-pin g, substantially as set forth.

5. The combination of a receptacle R, covered with a wrapping of textile material, the water-receptacle A, having the loop Z, hook n, and socket h, the curved perforated tube 0, communicating with the receptacle A, and the bracket j, substantially as set forth.

6. The combination of a receptacle R, covered with a wrapping of textile material, the water-receptacle A, the curved perforated tube 0, communicating with the receptacle A, and a stop-cock controlling the passage of water from the receptacle A into the tube 0, substantially as set forth.
